Methods : A total of 36 male Sprague Dawley rats were randomly divided into two groups, who were fed with highfat diet (experimental group, n=24) and normal basic food (normal control, n=12) respectively. At the end of the 12th week, the experimental group was randomly divided into two subgroups: model group and ecdysterone group, each group contained 12 rats. From the 13th week, the rats in the normal control group and model group were lavaged with normal sodium, and the rats in the ecdysterone group were lavaged with ecdysterone at 10 mg·kg-1·d-1. At the end of the 16th week, all rats were weighed, narcotized, sacrificed, and the liver index, biochemical indicators in serum and liver tissues and the hepatic pathological changes were observed. The expression of TNFα was detected by ELISA and the expression of NFκB was measured by immunohistochemical staining. Results : At the end 16th week in ecdysterone group, the serum levels of cholesterol (TC), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were reduced markedly (212±058 vs 263±024 and 5336±1848 vs 8460±3627, both P＜005; 14020±3595 vs 24359±3638, P＜001); the tissue content of malondialdehyde (MDA) was decreased evidently (18454±1645 vs 23928±2376, P＜001), while the activity of superoxide dismutase (SOD) was enhanced notably (942±052 vs 518±043, P＜001); the liver index was decreased significantly in comparison with that inmodel group (435±037 vs 504±046, P＜001); the degree of fatty degeneration and inflammation were relieved dramatically (546±037 vs 630±049, P＜001). The expression of TNFα and the levels of NFκB were significantly lower (4304±748 vs 6156±727 and 2465±539 vs 4504±746, both P＜001) in ecdysterone group compared with model group. Conclusion : The effects of ecdysterone in preventing NAFLD in rats could be related to the increase of SOD content in hepatic tissue and the decrease of MDA content, tumor necrosis factorα and NFκB.
Six patients with moderate to advanced primary carcinoma of the liver were treated in this hospital with perfusion chemotherapy and embolization through the regional portal vein under the guidance of B-ultrasongraph rather than (with) operatie catheteization of the portal vein. The results show that all the tumor masses were reduced in size after the treatment (1.2-3.2cm, average value 1.9cm). It might be a new way for treating the primary carcinom of liver. The detailed procedure is descibed and the effects are also discussed in this article.
Objective To explore the value of laparoscopic hepatectomy for small hepatocellular carcinoma (HCC) of non-peripheral type. Methods The clinical data of 34 patients with small HCC of non-peripheral type underwent laparoscopic liver resection from March 2008 to April 2011 in our hospital were analyzed retrospectively. Results Thirty-two patients received successful total laparoscopic hepatectomy without blockage of liver blood flow，and 2 were converted to open surgery. The operative time was （162±65） min （100-220 min） and the blood loss was （295±166） ml （100-750 ml）. There were postoperative complications in 4 patients， included cross-section bleeding in 2 cases and ascites in 2 cases. There were no complications such as biliary fistula， infection， carbon dioxide gas embolism， and so on. The mortality of perioperative period was 0. The postoperative hospital stay was （6±2） d （4-9 d）. The follow-up time was （23±7） months （5-42 months）. Thirteen patients developed intrahepatic tumor recurrence during follow-up. The overall and recurrence-free survival rate one year after operation was 90.6% （29/32）and 75.0% （24/32）， respectively. Conclusions Laparoscopic hepatectomy is a safe， feasible， and minimal invasive approach for small HCC of non-peripheral type，and it can be considered as a alternative treatment of HCC.
ObjectiveTo introduce the basic principles of commonly used assessment methods for liver function reserve, and compare the advantages and disadvantages of various assessment methods, so as to provide a reference for hepatectomy of patients with hepatocellular carcinoma (HCC). MethodThe literature on evaluation methods of liver reserve function in patients with HCC at home and abroad in recent years was searched and summarized. ResultsFrom the results of literature review, the Child‐Pugh score and indocyanine green discharge test were the most commonly used to assess preoperative liver function reserve for patients with HCC. The application value of other examinations such as albumin-bilirubin score, gadolinium-ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-enhanced MRI), nuclear medical imaging in predicting post-hepatectomy liver failure was gradually being explored. ConclusionsThe combination of clinical parameters and volumetric studies is used to assess preoperative liver function reserve for patients with HCC. The clinical applications of nuclear medical imaging and Gd-EOB-DTPA-enhanced MRI make up for the deficiency of local liver function reserve evaluation, which are important examinations to assess liver function reserve after conversion therapy in the future. However, more domestic studies are still needed to confirm their values.
ObjectiveTo review the causes, prevention methods, and therapies of the small-for-size syndrome (SFSS) in living donor liver transplantation (LDLT). MethodsThe literatures about SFSS in recent years were reviewed and summarized. ResultsThe donor’s age, graft steatosis level, MELD score of the recipient, portal hypertension, low outflow, and graft size were risk factors of SFSS. Ideal donor, splenectomy, ligating splenic artery, keeping a satisfactory intraoperative outflow, early diagnosis and active therapy could obviously decrease the incidence of SFSS. ConclusionThe risk factors of SFSS can be predicted before operation, and the positive actions can be used to prevent or cure the SFSS.
ObjectiveTo investigate the clinicopathologic features of intracranial anaplastic solitary fibrous tumor (SFT)/hemangiopericytoma (HPC) and diagnosis and treatment after liver metastasis.MethodThe clinicopathologic data of patients with intracranial anaplastic SFT/HPC who had metastasized to the liver and other organs after surgery were collected from 2003 to 2019 in the Second Hospital of Lanzhou University.ResultsAll 3 patients with intracranial anaplastic SFT/HPC underwent surgical resection and supplemented with conventional radiotherapy after operation. After the initial intervention treatment, 2 patients relapsed at 10 years and 7 years after the operation, and 3 patients had liver metastases at 11, 7, and 6 years after the initial intervention treatment. One of them was accompanied by uterus, lung, and vertebral body metastases.ConclusionsIntracranial anaplastic SFT/HPC has a high risk of recurrence and extracranial metastasis. Liver is a common target organ for metastasis of anaplastic SFT/HPC, liver metastasis is delayed after initial intervention of intracranial anaplastic SFT/HPC, it requires a long-term close follow-up.
